移动设备和物联网（IoT）的日益普及启发了Cloudlet概念的冒险，这是一个靠近边缘用户的“小数据中心”。如果他们可以在与Cloudlet服务器的单跳距离内访问所需的资源，那么许多研究人员都建议使用虚拟机（VMS）作为此类服务提供服务器容器的潜力 - 轻量级虚拟化工具，将LXC容器作为Cloudlet平台，以促进CRIU之间的容器迁移，因为CRIU（用户空间中的检查点/还原）已被选为迁移工具。网络（WAN）可能会遇到拥堵或网络失败，本文采用MPTCP（Multipath TCP）协议来应对挑战在MPTCP连接中建立的多个子量可以改善迁移过程的韧性，并减少迁移时间。有效增强迁移过程。
The growing popularity of mobile devices and Internet of Things (IoT) has inspired the advent of the Cloudlet concept—a "small data center" close to users at the edge. It is believed that the Quality of Experience (QoE) of end users would greatly improve if they can access required resources within a one-hop distance from Cloudlet servers. Over the years, many researchers have proposed using virtual machines (VMs) as such service-provisioning servers. However, seeing the potentiality of containers—a lightweight virtualization tool, this paper adopts LXC containers as Cloudlet platforms. To facilitate container migration between Cloudlets, CRIU (Checkpoint/Restore in Userspace) has been chosen as the migration tool. Since the migration process goes through the Wide Area Network (WAN), which may experience congestion or network failures, this paper adopts the MPTCP (Multipath TCP) protocol to address the challenge. The multiple subflows established within a MPTCP connection can improve the resilience of the migration process and reduce migration time. We have conducted a number of experiments to validate the proposed approach. The experimental results show that LXC containers are suitable candidates for the problem and MPTCP protocol is effective in enhancing the migration process.
